In addition, many special teams players may not make large contributions on defense, but might stick around in the league on a roster as primarily a special teamer for several years while never playing many meaningful snaps on the defensive side of the ball. Thus, in order to get a better look at what an aging curve for Wagner might look like, I narrowed things down using the methodology of a commenter suggested in the original article. Specifically, what I did was I looked at all linebackers who started twelve or more games in their rookie season and then looked at the age at which each of these players last started ten or more games. The data I looked at was players whose rookie season was between 1997 and 2009, a time period which allowed for a sample of 55 such linebackers. That is far from a huge sample, but it is large enough to begin to draw some basic understanding of the aging curve, while also representing players who are old enough that they are no longer active. Of the 55 linebackers who entered the league during this time period, only three remain active, including Derrick Johnson, Brian Orakpo and Clay Matthews.Two of those three players are edge defenders as opposed to interior off ball linebackers like Wagner, but just keep those names in mind because as they are still in the league, they could theoretically continue to pull the aging curve to the right in Wagner’s favor (they are represented in the data as points at 32, 32 and 35). Without too much more discussion, here is the data. Aging curve for NFL linebackers who started at least 12 games in their rookie seasonAge last started 10 gamesNumber of PlayersAge last started 10 gamesNumber of PlayersNow, I’m much more of a visual learner, and I’m sure many readers are as well, so here is that same data in chart form. Now, that obviously shows that linebackers careers enter the danger zone at some point in their late twenties, and that while the odds of Wagner continuing to contribute for the Hawks remains high, they start to diminish rapidly over the coming seasons. One topic of note specifically is that player aging is not a smooth and natural decline over time. Player aging in the NFL can be much more accurately looked at along the lines of a mortality distribution, as so many players are able to perform at a high level until all of a sudden a single injury forces them out of the game. Thus, looking at the preceding data from that standpoint, here is what the distribution of this data looks like when evaluated from a survivorship perspective.What that chart shows us is that of linebackers that start at least twelve games during their rookie season, we can expect around eighty percent of them to start at least ten games in their age 28 season. Once those players get past their age 28 seasons, however, is when a rapid decline is often seen. Thus, Wagner having started fifteen games in his age 28 season has entered the period of his career where things could get derailed by a single play. Obviously, that is not to say that he will be finished anytime soon, as full twenty percent of the players in the sample started double digit games in their age 33 season or later (this represents twenty-five percent of the players that made it to their age 28 season). That does, however, carry the implication that there is a three in four chance of Wagner not making it to his age 33 season. In fact, by the data in the sample, the odds of him starting ten or more games anytime in his age 31 season or older are roughly a coin flip.This is important to keep in mind simply because Wagner is already under contract for his age 29 season, meaning that any extension would begin with his age 30 season. Thus, that age 31 season where his availability based on the data from the sample is worse than winning a coin flip is going to be the second year of any extension, and that is considering the fact that he started ten or more games in his age 28 season. Now, I know some commenters are going to jump right to the comments and chime in that the data are not representative of Wagner because of the fact that he’s different because he’s a five time Pro Bowl, four time All Pro linebacker, but that is not going to make much of a difference. Yes, his skills and ability will be coming from a higher peak, so he will not likely be subject to a skill decline that prevents him from playing at a high level going forward, but the data is filled with samples of just such players. For example, while he’s not in the data set, K.J. Wright is an example of how age can sneak up on a player in their late twenties. Between the time he was drafted in 2011 and 2017 Wright missed just five games over seven seasons, and then in 2018 missed eleven games due to a knee injury. Similar examples from high level players at different positions for the Seahawks can be seen in names like Kam Chancellor Chris Carson Jersey Green , Richard Sherman and Doug Baldwin. Chancellor missed just ten games due to injury (this excludes the two games he missed in 2015 due to his holdout) over the first seven seasons of his career before a garbage time neck injury brought his career to a sudden halt at age 29. Sherman didn’t miss a snap over a more than ninety game streak covering parts of seven seasons until all of a sudden a single injury ended his time with the Hawks. Baldwin had missed just two games over his career, until a myriad of injuries caused him to miss three games in his age thirty season, and put his future in question following at least three offseason surgeries. Looking specifically at the linebacker position, there are plenty of examples, including Al Wilson who was an All Pro linebacker for the Denver Broncos until a neck injury during his age 29 season brought his career to an abrupt halt. Jamie Sharper played every single game for the Houston Texans and Baltimore Ravens over a period of eight seasons, but a single injury eight games into his age 30 season ended his career. Patrick Willis was a seven time Pro Bowler and five time All Pro, until a toe issue caused him to miss ten games at age 29 and led him to hang up his cleats. In short, here’s the linebacker survivorship chart once a player has started at least ten games in their age 28 season.In summary, Wagner is likely to continue to perform at a high level, but the odds of an injury bringing his career to a close are not insignificant. Thus, while the team has seen poor outcomes from third contracts it has handed out in the past, including to Chancellor and Marshawn Lynch, that doesn’t mean it should not work to extend Wagner. The team has the ability and opportunity to Wagner, but it should most certainly take advantage contract structures which carry less risk for the team than some of the contracts the front office has signed in the past. ATLANTA (AP) — The Rams moved from St. Louis to Los Angeles, had seven head coaches and used 20 starting quarterbacks since losing to the New England Patriots in the Super Bowl 17 years ago.Meanwhile, Bill Belichick and Tom Brady are still here and they’re going for their sixth NFL title in the rematch Sunday.Steven Jackson, a three-time Pro Bowl running back during his 12 seasons in the NFL, experienced the turnover with the Rams and briefly enjoyed the Patriots way.Selected by the Rams in the first round of the 2004 draft, Jackson had eight straight 1,000-yard rushing seasons for St. Louis. But he didn’t appear in a playoff game after his rookie year until he signed with the Patriots late in the 2015 season.Jackson scored his only career playoff touchdown in the AFC championship game against Denver. New England hasn’t lost a title game since that one.“I played for six of those coaches. The turnover, I had to endure that and then to end my career in New England and see the longevity and how well they know each other, you could see why they’re successful,” Jackson said.“You could see why they know what plays to call, what Tom runs well, what the other defensive unit runs well because they have the continuity there, they haven’t had a lot of change and they run the same offense and defense still.”Between Kurt Warner to Jared Goff, the Rams went from Marc Bulger to Case Keenum. Sam Bradford was supposed to be the answer when he was drafted No. 1 overall in 2010. But Bradford never had a winning season and was traded to Philadelphia for Nick Foles in 2015 after tearing his ACL two straight seasons.Guys such as Gus Frerotte, Chris Chandler, A.J. Feeley and Sean Mannion have started for the Rams over the past 17 seasons. Even Trent Green came back and lined up under center one more time for the Rams in 2008 after his injury in 1999 opened the door for Warner to begin his Hall of Fame career.Coaches included Mike Martz, Jim Haslett, Steve Spagnuolo and Jeff Fisher.The Rams had a revolving door until Sean McVay took over as coach in 2017 and led them to consecutive NFC West titles with Goff, the No. 1 overall pick in 2016.McVay marvels at New England’s accomplishments over the past two decades.“When you look at these guys and what they’ve done in terms of consistency, where that’s really the truest measurement of performance, and nobody’s done it better than they have over the last handful of years, that’s why you have so much respect and appreciation for them,” McVay said.Brady has certainly evolved since leading the Patriots to an upset over the “Greatest Show on Turf” version of the Rams for his first Super Bowl championship. At 41, he relies more on his wisdom and knowledge.“I think the preparation is different but in some ways it’s easier for me because I’m very efficient in what my routine is because when I was a young player you’re studying, you’re watching tape but you don’t really know what you are looking for,” Brady said.“Now I have a plan every time I want to sit down and study, how to understand an opponent, how to understand coverages, how they work and how to put together a plan with (offensive coordinator) Josh (McDaniels) that we can have confidence in. I was so young and naive and as a young player. I’m probably a little less naive now but I still love the competition. I still love trying to win football games. It’s the first love of my life and I’m still enjoying it now.”Brady has always credited his longevity to his rigorous training with Alex Guerrero. He insists he’s playing beyond this season and wants to keep going until he’s 45.“A lot of work that has been done with Alex over the past 15 years has given me that opportunity and I feel like that’s something I owe myself to see how I can keep pushing the envelope because it is unchartered territory and when you’re in uncharted territory, you are trying to prove things to yourself, too,” Brady said.“I’m very confident in my routine. I feel great this time of year. There’s nothing I’m dealing with and part of it is being in a good place mentally and physically.“The reality is I don’t think many people thought I would be playing like this, even though I had a great belief that I would.”
